BELT-HOOK- FASTENING MACHINE.

Application filed January 2, 1917.

I fastening belt hooks or staples into the ends of belts, it being designed for use with the common and Well known Webb type of belt fasteners. In the process of fastening a plurality of belt hooks or staples in the end of a belt it is desirable that in the final attachment of staples to the belt end, the legs thereof be embedded in the belt end, this requiring a very heavy pressure or force applied to the belt staples, My invention has for one of its objects the provision of mechanism including a relatively stationary jaw 0r anvil and a movable pressure jaw between which the belt hooks or staples are bent for attachment to the end of a belt, and of mechanism for operating the pressure jaw toward the anvil so that on the beginning of its movement the pressure jaw moves at a relatively high rate of speed which diminishes as the pressure jaw moves toward the anvil until at the final portion of its movement toward the anvil it is relatively very slow. With the mechanism for actuating the same operated at a constant speed and under a constant force the pressure which may be transmitted by the jaw in the final portions of its movement is very great. A further object of the invention consists in the provision of novel mechanism for actu ating the pressure jaw which may be quickly and easily operated by means of a crank and gearing connections interposed between the crank and the pressure jaw. Many other objects and purposes together with novel mechanism for attaining the same will be apparent as my invention is disclosed, reference being had to the accompanying drawings, in which;

Like reference characters refer to like parts throughout the several views of the drawings.

In the construction of the machine a sup port is provided, preferably as a casting having spaced apart sides 1 and 2 connected at their lower edges by cross pieces A shaft 4 is mounted between the sides 1 and 2 at the upper rear corner thereof, as shown in Figs. 1 and 2, and carries thereon a pinion 5 and rollers 6 each of which is provided with a flange 7. Pinion 5 is'keyed to the shaft while the rollers 6 are loosely mounted thereon, the pinion being interposed between the rollers and flanges 7 formed on the rollers at each end of the pinion.

A bar 8 is fixed to one end of shaft 4 and provided at each end with a handle 9 for manual operation thereof. In front of the shaft 4; a second shaft 10 is mounted between the sides 1 and 2 of the support, on which a pinion 11 is loosely mounted, said pinion being of a length equal to the distance between the sides 1 and 2. A gear 12 considj erably larger in diameter than the pinion 11 is passed over said pinion and meshes with the pinion 5 heretofore described, it being apparent that the pinion 11 extends for a distance to each side of the gear 12. A pair of racks 18 mesh with the pinion 11, one at each side of the gear 12, and at their rear edges bear against the rollers 6, being held between flanges 7 of'said rollers and the sides 1 and 2. Each rack at its lower end is pivotally connected to the rear end of a member 14, said members being pivotally connected at their front ends to the sides 1 and 2 of the support as shown. Each of the members 14 on its upper edge is formed with a curved surface as best shown in Fig 2.

A lever 15 is pivotally mounted between rearwardly extending portion of said lever is relatively long and on its end carries two rollers 17, one on each side, which bear against the upper edges of the members 1% heretofore described, the forwardly eX- tending portion of the lever passes beyond. the front edges of sides 1 and 2 and is formed into a bearing to receive a shaft 185 on which are pivotally mounted jaw supports 19, one at the outside of each of the sides 1 and 2 and extending upwardly and to the rear and then curved forwardly, there being a pressure jaw secured to and be tween and on the under side of said jaw members at their upper ends. Rollers 21 are mounted upon a shaft 22 which is interposed between and connected to said jaw members back of the pressure jaw. These rollers ride on the upper edges of the sides 1 and 2 of the supports which are formed at such points to properly guide the rollers and the jaw members with which they are associated.

A bar 23 is cast integral with and is located between the front edges of the sides 1 and 2, it carrying on its upper surface a hardened plate or anvil 2a which is permanently secured in any suitable manner. Said anvil at its rear edge is formed with a. series of spaced tongues 25. Directly back and a little above the anvil 2% a bar 26 is located, it having rearwardly projecting ears 2? through which a pin 28 passes for pivotal mounting of the same between the sides 1 and of the support. The forward edge of the member 26 is likewise fashioned with a series of spaced tongues 29 adapted to enter the slots between the tongues previously described. Normally the slotted bar 26 is elevated by a coil spring 30 interposed between its lower side and the bar 23 until stopped by contact of shoulders 31 on said bar against the forward edges of the sides 1 and Holes in alinement are made through the tongues 29 whereby a pin. 32 may be removably inserted through all of the holes for the purpose of retaining the belt hooks or staples 33 in place in parallelism to be acted upon by the pressure jaw 20.

In operation a plurality of belt hooks or staples 33 suflicient for the width of the belt end are inserted in the slots between tongues 29 said staples each having diverging arms which terminate in attaching;

prongs turned toward each other. Theopposits ends of the arms of a staple are con neeted by an integral. curved bend or bite in front of which the retaining pin 32 passes shown in Fig. The belt end 34 to vhich the staples are to be secured is inserted between the prongs and one of the handles 5 grasped to turn shaft 4 whereupon racks l3 are elevated carrying members 14 therewith as shown in Fig. 2 and causing a corresponding elevation of the rear end of lever and a depression of the forward end of the arm l5 thereof. In this manner the jaw members 19 are moved from the dotted line position indicated in Fig. 2 to the full line position. It is apparent that during the fore part of the movement during which practically no work is being done, the elevation of the rear end of levers 15 and the corresponding forward and downward movement of the pressure jaw 20 is rela-v tively rapid. But as the jaw 20 comes into contact with the uppe' arms of the staples 33 the movement of the jaw decreases and becomes increasingly slower. With the continuation of the movement of the pressure jaw the upper arms of the belt hooks or staples are bent downward and. the attaching prongs thereon inserted into the end of the belt and at the same time the attaching prongs on the lower arms lying on the anvil are inserted into the end of the belt from the opposite side. hen this operation has begun it is not necessar I to thereafter hold the belt end with one hand and both handles 9 may be grasped for operation of the mechanism whereby a very heavy pressure against the arms of the staples and against the end of the belt 34 may be produced said arms of the staple being easily embedded so as to lie flush with the surfaces of the belt end. At the same time as the staples are attached to the belt end, the member 26 is depressed and the force of spring 30 overcome so that the proper position of the curved portions of the belt staples with re spect to the end of the belt is secured, this being of advantage in permitting use of the machine with belt hooks and staples of varying sizes.
